Hydration of Cement

Hydration of Cement

Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...

Alkali Aggregate Reaction in Concrete

Alkali Aggregate Reaction in Concrete

The alkali-aggregate reaction in concrete involves natural siliceous minerals in aggregates reacting with alkaline hydroxides derived from cement alkalis. This reaction forms an alkali-silica gel that absorbs water, swells, and increases in volume, which is confined by the surrounding cement paste, creating internal pressures that crack and disrupt the concrete. The extent of expansion and damage can be partly attributed to the alkali-silica reaction's osmotic hydraulic pressure and the...

Transition Zone

Transition Zone

The transition zone in concrete is a critical area where aggregate meets cement paste, marked by a distinct porosity and weakness compared to the surrounding material. The adhesion around the aggregates is primarily due to Van Der Waals forces. The voids within this zone influence its robustness; initially, it is less durable than the surrounding bulk mortar due to larger voids. Initially, when concrete is compacted, a higher water-cement ratio near the aggregates leads to the formation of...

Sulfate Attack on Concrete

Sulfate Attack on Concrete

Sulfate attack on concrete is a deterioration process characterized by a whitish discoloration beginning at the edges and corners, accompanied by cracking and spalling. This phenomenon occurs when sulfates react with the components of hardened concrete, forming compounds like calcium sulfate and calcium sulfoaluminate which occupy more space than the substances they replace, causing the concrete to expand and disrupt.
Sulfates from sources like soil, groundwater, or industrial effluents...

Porosity in Cement Paste

Porosity in Cement Paste

The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
The balance of water to cement in the mix is critical—it...

Bonding and Strength of Aggregate

Bonding and Strength of Aggregate

The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...

Summary

This summary is machine-generated.

A new calcium-silicate cement forms a unique "mineral infiltration zone" at the dentin interface, enhancing mineralization. This differs from glass-ionomer cements, which show acid-based penetration.

Background:

Understanding dentin-restorative material interfaces is crucial for durable dental restorations.
Calcium-silicate cements offer potential advantages over traditional glass-ionomer cements (GIC).
The interaction between restorative materials and dentin collagen influences long-term stability.

Purpose of the Study:

To investigate the interfacial properties of a calcium-silicate cement (Biodentine™) and a GIC with dentin.
To characterize the formation and nature of the interfacial layer created by Biodentine™.
To compare the interfacial interactions of Biodentine™ and GIC with dentin.

Main Methods:

Confocal laser scanning microscopy (CLSM)
Scanning electron microscopy (SEM)
Micro-Raman spectroscopy
Two-photon auto-fluorescence and second-harmonic-generation (SHG) imaging

Main Results:

Biodentine™ forms tag-like structures and a
mineral infiltration zone
]
The alkaline hydration products of Biodentine™ degrade dentin collagen, creating a porous interface.
This porous zone facilitates ion permeation (Ca(2+), OH(-), CO(3)(2-)), leading to increased mineralization.
GIC penetration is characterized by polyacrylic and tartaric acids and their salts, unlike Biodentine™'s mineral infiltration.

Conclusions:

A novel interfacial interaction, the
mineral infiltration zone
, is proposed for calcium-silicate cements.
Biodentine™ promotes dentin mineralization at the interface through a unique degradation and infiltration mechanism.
This study highlights distinct interfacial behaviors between calcium-silicate cements and GICs with dentin.
